🔬 Common Scientific Applications

🔁 Redox viability assays: Blue resazurin → pink fluorescent resorufin upon reduction; proxy for cellular/metabolic activity.

🧪 High-throughput screening (HTS): Plate-based cytotoxicity and proliferation assays; dehydrogenase activity readouts.

🦠 Microbial viability & respirometry: Growth monitoring in bacteria/yeast; anaerobic/oxygen-reduction indicator in culture media.

🧫 Biofilm metabolism: Non-destructive metabolic tracking of biofilm formation and treatment response.

🔬 Enzyme & pathway kinetics: Oxidoreductase assays; metabolic flux/energy state evaluations in vitro.

🧯 Environmental & ecotox testing: Rapid toxicity screens in water/soil microcosms using metabolic reduction as endpoint.

💧 Microfluidics & organ-on-chip: On-chip viability/metabolism reporter for continuous perfusion systems.

📊 Instrumentation/calibration: Fluorescence reference via resorufin (Ex ~560–570 nm, Em ~580–590 nm; matrix-dependent).

R&D use only. Signal depends on cell type, density, incubation time, and matrix; verify excitation/emission on your instrument and consult the SDS/CoA for your lot.
